Constructor Detail

SignatureFragment

public SignatureFragment(FragmentList listToSign,
                         GalePrivateKey priv)
                  throws java.security.NoSuchAlgorithmException

Constructs a new signature fragment with a bunch of data and a key to sign with. Does not keep a reference to the key.

Parameters:

listToSign - the fragment list to embed in this SignatureFragment, signed by the private key given by priv.

priv - the non-null private key to sign with

SignatureFragment
